SPECIFICATION forming' part of Letters Patent No. 228,244, dated June 1, 1880.

Application filed July 14, 1879.

To all whom it may concern:

vBe it known that I, GEORGE BOHNER, of Chicago, Cook county, State of Illinois, have invented a new and useful Improvement in ExtensionChandeliers, of which the following is atull description, reference being had to the accompanying drawings, in which- Figure l is a front elevation. Fig. 2 is a side elevation. Fig. 3 is a vertical section.

rlhis invention relates to devices by the use of which the lamps ot a chandelier can be easily raised and lowered and held in any given position.

I have heretofore obtained Letters Patent ofthe United States relating to the same thing, the object being' accomplished by mechanism in sonic respects quite dii'erent from that now shown. In that patent the lamps are raised by means ot' springs arranged in barrels having cogs on their peripheries, which engage with holes in a tube.

I now have devised a telescopic tube and cords ruiming through the same, combined with other parts, as hereinafter fully described, by means ot' which devices the desired object can be accomplished.

In the drawings, A B C are three sections ot' a telescopic tube. The central section, C, is to be provided with a hook or otherl suitable device, by means ot' which the chandelier can be connected to a ceiling, while the lower end ot' the outer section, A, is to be connected to the frame in which the barrels which contain the springs are supported, which frame is marked D.

E are two barrels, which rotate on pins in the frame or head D. Within each barrel is a helical spring, a, so arranged that it will wind up when the lamps are drawn down.

F is a short tube, connected at its upper end to the head D, and provided with aca-p at the other end.

I) b are cords, which are wound upon the barrels E. Thelower end of each cord is secured to one of the barrels, and both cords pass up through the inner section of the telescopic tube, as shown in Fig. 3, and their upper ends are fastened in some suitable manner to such inner section, O. As shown, they are connected to a pin, o, which passes through C.

G is a rod located Within the tube F, on the upper end of which rod is a conical head, d, so arranged that when in position, as shown in Fig. 3, it will be between and in contact with the barrels E. This rod G passes through and is connected toa bar, H, which projects through slots f in the sides ofthe tube F.

e is a spring around the lowerend of the rod G and beneath the bar H. Said spring is so arranged that its tendency is to hold this rod and conical head d up, as shown in Fig. 3, and when in this position the barrels E cannot rotate.

In use, when the lamps are at their highest point, the several parts will be in the position shown in Figs. 1,2,and 3. By taking hold ofthe bar H the operator can draw down the rod G, withdrawing the head d from contact with the barrels. Then the lamps can be drawn down as far as thetelescopic tube will permit, at the same time winding up the springs a.. lf the rod G be then released, the head d will again be carried up by the action of the spring e, and, coming in contact with the barrels, will hold them in the position in which they have been placed. The lamps can be again raised by withdrawing the head d from between the barrels E, when the action of the springs d will raise the chandelier.

If the springs a are not strong enough to carry the lamps to their highest point, the operator can aid them by pushing upward.

I have not shown the lamps, but they are to be supported in cups at the ends ot' arms secured to the-tube F or to the head D, as is customary.

I have shown three sect-ions in the telescopic tube. A greater orless number may be used. This telescopic tube might be located below the head D instead of above it.

I do not limit myself to the particular stop d shown, but nd this convenient when the parts are arranged as shown. It' the telescopic tube be located below the head, a different stop must be provided.

The cords b b may be made of metal or other suitable material. In place of cords suitable metal bands might be used, passing through the telescopic tube.

I am aware that cords and metal ban ds have been used in connection with extension-chandeliers; but I am not aware that the same IOO 2. In an extension-chandelier, the combination of the telescopic tube, cords b b', passing through such tube, drums E. springs a, the 15 rod G, having conical head d, and spring e, substantially as and for the purpowff specified.

GEORGE BOHNER.
